    An engineering / manufacturing question

    One for you techie's. I'm thinking of making my own quick release cocking arm pins for HW's. Mild steel and case harden or stainless? Mild steel easier to machine, but then heat treatment or stainless, which is tougher but harder to machine. I'd welcome your thoughts...

    MS *& CH: I'd hate to have an SStl pin stuck in there to try and drill out, the bloody stuff work hardens too quickly!

    I'm pretty sure they're m/stl. Possibly case hardened, but as that applies to the top 20 thousandths of a millimetre you can cut / drill through the hardened surface. It's probably the best and the cheaper option for manufacture. Or, straight m/stl?

    I personally wouldn’t use mild steel. I’d use 304 stainless (which is easy to machine) or silver steel.

    If I don’t reply to your comments it’s probably because you’re on my Ignore list.

    I did a few for people last year and was going to case harden mild steel but ended up making them out of 304. They all seem quite happy with them.

    What about 303 which? is a lot easier to machine than 304.
